magma comes from the outer core and when an earthquake or something happends, a crack froms and the pressure of lava shoots up like a geyser.

∙ 7y agoMagma in the mantle rises through the crust because pressure builds up in the mantle and forces the magma to go up through the crust above, or because the pressure in the mantle pushes the magma upwards through the crust.

∙ 12y agoSince magma is hot, it is usually less dense that the surrounding matter, so it rises.

∙ 13y agoMagma in the mantle rises through the crust because pressure is always wanted to be released and when there is a weak spot in the crust magma automatically rushes to the surface.

Does the magma and lava from a volcano come from the mantle?
Yes it does , The magma finds gaps through the crust ( oceanic or continental) and comes up as a volcano. It is originally in the mantle.
Is it true that hotspots form where a plume of magma rises through the crust from mantle?
True
What are tectonic made of Magma and solid mantle crust and magma crust and solid mantle solid rock and molten rock?
Igneous rock
Why does magma rise through the crust above it?
Pressure builds in the magma chamber forcing it upward through faults in the crust
Molten rock under the ground?
yes there is its called the mantle its under the crust
What is an area where magma from deep within the mantle melts through the crust above?
Hot spot.

What is the hypothesis of volcanoes?
Magma from the mantle of the earth is forced up through fissures in the crust of the earth.
Where do you get your magma from?
Magma comes from the melting of material in the crust or upper mantle.
Molten rock under the ground?
yes there is its called the mantle its under the crust
Magma forms when solid rock in the crust and upper mantle?
Cools ^ If you took this answer then is Magma relevant to Ice? Magma forms when the solid rock in the crust and upper mantle melts. ^Why not erase it then?
Where does magma originate?
Magma originates from within the earth's interior; in the crust or mantle.
Why does magma rise to the crust above it?
Magma rises through the crust above it because of pressure and depending on the magma (Pahoehoe or Aa). Pahoehoe is thin and runny and pours outside of the crust but, Aa is think and chunky and it can not pour out of a crack in the crust. It is more likely to blow out.
Is magma released from volcanoes material from the core?
No, magma is not material from the core of the Earth. Magma is molten rock that is generated in the Earth's mantle, which lies between the core and the crust. Magma can rise to the surface during volcanic eruptions, forming lava flows or erupting explosively.
